Struct BarEncodingBits

pub struct BarEncodingBits(/* private fields */);

BAR in-band encoding bits.

The low bits of the BAR are not actually part of the address. Instead, they are used to in-band encode various bits of metadata about the BAR, and are masked off when determining the actual address.
